Table 418 shows the comparative rank order of those schools of which records appear 

 in both series. There is some tendency for camps to remain at the same level. Four camps 

 remain in the same quartile and two of these are in exactly the same position in both series. 

 Six camps move one quartile only, and only two camps move as much as two quartiles. The 

 last four camps in the list, which are all located in the South, seem to form a homogeneous 

 group among themselves. 



Table 418. 



-Comparison of rank order of camps of third and fourth series officers' training schools; rank based on percentage 



of A and B grades combined. 



After the fourth series of officers' training schools a consolidation of the work took place. 

 Four central officers' training schools for infantry were established at Camps Lee, Pike, 

 MacArthur and Grant. There were also other schools for training officers in other branches 

 of the service. Classes were started in these schools every month, and in most of the camps 

 psychological examinations were given to each class soon after its entrance to the school. 

 Examination alpha was used. 



The data concerning the results of this testing appear in table 419 and consist of 

 some 2,000 records chosen in the principal sampling from the four infantry schools, records 

 of 917 candidates in the machine-gun school at Camp Hancock, of 1,099 men in the training 

 school for engineering officers at Camp Humphreys, and of 261 men in the chaplains' school 

 at Camp Taylor. 



Two points should be held in mind in examining these data. In the first place, the 

 psychological ratings were used to a large extent in the selection of candidates for the schools 

 of the fifth series and few men were admitted to the schools if their rating fell below C. There 

 are also a great many men who took the examination at the school for the second or even the 

 third time. It is possible that this last fact does not affect greatly the letter grade of the man 

 but it may make a slight difference in the percentage of A and B grades obtained by the group. 



Table 419. — Percentage distribution of letter grades for groups of officers' training camps of the fifth series. 



As shown in table 419, all the candidates do a little better than the officers selected by 

 the principal sampling. The difference, however, is slight and not significant. 



On the basis of the percentage of A and B grades obtained, the candidates of the fifth series 

 do much better than those of the third and fourth series. This comparison is hardly valid, 

 however, because of the selection of candidates on the basis of intelligence rating as mentioned
